9/23/2023 0 Comments Buffalo mweather![]() Every 10 years, the Normal is recalculated by including the most recent 10 years and removing the earliest 10 years. The time period of the climatic Normal is updated every 10 years, so a climate Normal can change. The years that make up the current climate Normal (as used for July 2023) are 1991 to 2020. The choice of 30 years is a period of time deemed sufficiently long to provide a stable average (filtering out short-term variability) and assuring comparability between data collected at different stations. Mandated by international agreement, since 1901 nations have routinely calculated a 30-year climate Normal. So, July 2023 was a warmer than Normal month, when compared to a prescribed 30-year period. For July 2023, the months overall average temperature was 72.8⁰F which was 1.1⁰F above Normal. Reading the table, we can see that July 6 th, in Buffalo, was 10 degrees above Normal for that date. Note the table below, which shows Buffalo’s weather data for July 2023 (shown here are the first 23 days of the month), where the 5 th column, labeled as ‘DEP’, shows each day’s departure from Normal. Daily and monthly temperature departures from Normal are routinely reported with the National Weather Service (NWS) monthly summaries of local climatological data and relayed to the public via news media.įor illustration, I’ll focus on the month of July which typically is Buffalo’s warmest month of the year. It is defined as the average and extreme values of a weather parameter for a place over a period of 30 years. With weather, a normal, or more specifically a climate “Normal” (notice emphasis on the uppercase ‘N’), has a more precise meaning. Even under benign conditions, a typical weather broadcast often compares current weather conditions to that of the normal, with wording to the effect of “yesterday’s temperature was above normal.” While we might interpret normal as typical, usual, expected, or common, the weather-related definition is different or, more precisely, contains an important caveat. Forecasters warned of rapidly changing road conditions and near-zero visibility for drivers, with the potential for snow to fall at a rate of 2 inches per hour during the most intense periods.News headlines accentuate the occurrence of abnormal weather – heatwaves, excessive rain, widespread flooding, etc. More than a foot was possible between Thursday and Saturday in parts of Michigan, according to the National Weather Service, with some of the heaviest amounts expected in the Grand Rapids area. Other regions were bracing for lake-effect snow. “Areas within these snow bands will experience visibility dropping to near zero at times and covered roadways that will make travel extremely hazardous, if not impossible.” “As a result of the potentially paralyzing event, lake effect snow warnings are in effect downwind of the aforementioned lakes,” forecasters with the prediction center wrote Thursday morning. The Buffalo weather office said that stronger winds near the shoreline, gusting at times to 35 miles per hour, combined with the heavy snow, could create visibility as low as just a few hundred feet. ![]() ![]() “Total snow accumulations of 2 to 4 feet in the most persistent lake snows” is possible in the Buffalo, N.Y., region, according to a warning issued by the weather office. ![]() They also predicted that higher totals measured in multiple feet were possible in some areas near Buffalo over the course of the storm. Forecasters said that the probabilities for snow were fairly high for over a foot of snow within 24 hours ending Friday evening. ![]()
